I actually think the current one works well with some bigger lenses - the 70-300L, for example.

Me, I hate EVFs, and definitely don't want one. As has been said, decent AF is what they should work on!

Me too. I had a NEX 7 and did not like the EVF, even though I thought it was implemented well. I've adjusted to shooting with the screen on the M and do not need or want a viewfinder for this. I have a dslr for uses where it is helpful...
